How to improve eyesight: here are some habits, foods to eat and specific exercises to strengthen the eyes and avoid unnecessary ocular tension.
It is not possible to correct vision problems without the intervention of an ophthalmologist and there are no simple and quick solutions to solve them. However, if we adopt healthy habits and an adequate diet, we can help keep our eyes healthy in a natural way. In any case, it is always good to seek advice from your trusted ophthalmologist.
Visual disturbances, the most frequent causes
The best time to keep our eyes healthy starts when our eyesight is still very good! We pay attention to the movements we make with our eyes: we often tend to make movements that can compromise their health: when for example we squeeze them.
Among the most common causes attributable to visual disturbances we have:
- The constant use of PCs, tablets, smartphones or TVs: devices that subject the eyes to fatigue with consequent vision problems.
- Frequent use of contact lenses: they can limit the production of tear fluid leading to dryness and an increased risk of eye infections.
- Constant exposure to dust or pollen that causes redness, tearing or burning.
- Use of artificial lights: strain the eyes by damaging their vision.
- Prolonged and unprotected exposure to the sun's rays: they can compromise the health of the retina.
How to improve eyesight
As already mentioned, it is impossible to correct visual disturbances without having to resort to lenses or surgery, we can still improve the sight and health of our eyes thanks to some simple precautions that we will propose below.
Different eye exercises and techniques can be effective in improving eyesight and especially myopia. This is the case, for example, with acupressure. However, there is no official confirmation that these exercises produce concrete results!
Combat eye strain
In many cases, the lowering of vision can be represented by excessive ocular tension. Many hours in front of the PC or TV, or an excessive and unconscious effort of the eyes can compromise their health. This tension can also be the cause of frequent headaches.
To relax the eyes, we can apply the palming technique:
- Rub your hands to gain some heat.
- Place your elbows on the table and your palms on your eyes, without squeezing.
- Relax for a couple of minutes in this position trying to reduce any tension in the eyes or the muscles around them
- At the end of this exercise, you generally have greater sharpness in vision.
We can preserve the health of our eyes and support them in their strenuous work through a food diet, which involves the use of beneficial and protective substances. Regular consumption of foods rich in micronutrients will help us keep our eyes and our body in general fit.
Here are the vitamins and antioxidants that can preserve the health of our eyes
- Vitamin A: Vitamin A deficiency can affect our supply of rhodopsin, a fundamental pigment that allows us to see in the dark and in low light situations. Its deficiency also leads to dry eyes, predisposition to infections and ulcerations.
- Vitamin D: the adequate supply of this vitamin protects the retina from inflammation and helps to reduce eye redness.
- Vitamin C: in addition to protecting the body from attack by free radicals, it is also essential for eye health! It helps, in fact, to prevent degenerative diseases and corneal ulcers, and also helps to counteract hardening of the eye and to prevent and eliminate infections.
- Vitamin E: helps prevent eye disorders such as cataracts and AMD (adult macular degeneration). It is available in foods such as cereals, almonds, corn oil, wheat germ oil, hazelnuts
- Lutein: this is a pigment present in the macula, the central part of the retina, which protects the eye from strong light. It acts as a filter and prevents harmful radiation from reaching and damaging the retina. A lutein supplement promotes this defense process by naturally improving vision.Lutein is found naturally in green leafy fruits and vegetables, such as spinach, broccoli and Swiss chard
- Vitamin B2: its deficiency can lead to burning, sensitivity to light, itching, tearing and in extreme cases, can cause paralysis of the eye muscles. This vitamin is found in liver, cereals, yeast and eggs.
